Non-protein clostridial toxin compositions

ABSTRACT

Pharmaceutical compositions that stabilize a Clostridial toxin active ingredient are described. The compositions can be liquid or solid compositions, and comprise a surfactant and an antioxidant. In some embodiments, the compositions comprise a surfactant selected from a poloxamer and a polysorbate; an antioxidant selected from methionine, N-acetyl cysteine, ethylenediaminetetraacetic acid and combinations thereof; and, optionally, a tonicity agent and/or a lyoprotector selected from, for example, trehalose and sucrose.

FIELD

The present invention relates to solid and liquid pharmaceutical compositions comprising a clostridial toxin active ingredient and one or more non-protein excipient.

BACKGROUND

A pharmaceutical composition is a formulation which contains at least one active ingredient (such as a Clostridial toxin) as well as, for example, one or more excipients, buffers, carriers, stabilizers, preservatives and/or bulking agents, and is suitable for administration to a patient to achieve a desired diagnostic result or therapeutic effect. The pharmaceutical compositions disclosed herein have diagnostic, therapeutic and/or research utility.

For storage stability and convenience of handling, a pharmaceutical composition can be formulated as a lyophilized (i.e. freeze dried) or vacuum dried powder which can be reconstituted with a suitable fluid, such as saline or water, prior to administration to a patient. Alternately, the pharmaceutical composition can be formulated as an aqueous solution or suspension. A pharmaceutical composition can contain a proteinaceous active ingredient. Unfortunately, a protein active ingredient can be very difficult to stabilize (i.e. maintained in a state where loss of biological activity is minimized), thereby resulting in a loss of protein and/or loss of protein activity during the formulation, reconstitution (if required) and storage of the pharmaceutical composition prior to use. Stability problems can arise due to surface adsorption of a protein active ingredient, physical instability, such as, e.g., denaturation or aggregation, or chemical instability, such as, e.g., cross-linking, deamidation, isomerization, oxidation, formation of acidic or basic species, Maillard reaction, and fragmentation. To prevent such instability, various protein-based excipients, such as albumin and gelatin, have been used to stabilize a protein active ingredient present in a pharmaceutical composition.

Unfortunately, despite their known stabilizing effects, significant drawbacks exist to the use of protein excipients, such as albumin or gelatin, in a pharmaceutical composition. For example albumin and gelatin are expensive and increasingly difficult to obtain. Furthermore, blood products or animal derived products such as albumin and gelatin, when administered to a patient can subject the patient to a potential risk of receiving blood borne pathogens or infectious agents. Thus, it is known that the possibility exists that the presence of an animal-derived protein excipient in a pharmaceutical composition can result in inadvertent incorporation of infectious elements into the pharmaceutical composition. For example, it has been reported that use of human serum albumin may transmit prions into a pharmaceutical composition. Thus, it is desirable to find suitable non-protein excipients, such as, e.g., stabilizers, cryo-protectants and lyo-protectants, which can be used to stabilize the protein active ingredient present in a pharmaceutical composition.

The unique characteristics of Clostridial toxins further constrain and hinder the selection of suitable non-protein excipients for a pharmaceutical composition comprising a Clostridial toxin active ingredient. For example, Clostridial toxins are large proteins having an average molecular weight of approximately 150 kDa, and are further complexed with non-toxin associated proteins that increase the size to approximately 300-900-kDa. The size of a Clostridial toxin complex makes it much more fragile and labile than smaller, less complex proteins, thereby compounding the formulation and handling difficulties if Clostridial toxin stability is to be maintained. Hence, the use of non-protein excipients, such as, e.g., stabilizers, cryo-protectants and lyo-protectants must be able to interact with the Clostridial toxin active ingredient in a manner which does not denature, fragment or otherwise inactivate the toxin or cause disassociation of the non-toxin associated proteins present in the toxin complex.

Another problem associated with a Clostridial toxin active ingredient, is the exceptional safety, precision, and accuracy that is necessary for at all steps of the formulation process. Thus, a non-protein excipient should not itself be toxic or difficult to handle so as to not exacerbate the already extremely stringent requirements.

Still another difficulty linked with a Clostridial toxin active ingredient, is the incredible low amounts of Clostridial toxin that is used in a pharmaceutical composition. As with enzymes generally, the biological activities of the Clostridial toxins are dependant, at least in part, upon their three dimensional conformation. Thus, a Clostridial toxin is detoxified by heat, various chemicals, surface stretching, and surface drying. Additionally, it is known that dilution of a Clostridial toxin complex obtained by the known culturing, fermentation and purification methods to the much lower concentration used in a pharmaceutical composition results in rapid inactivation of the toxin. The extremely low amount of a Clostridial toxin active ingredient that is used in a pharmaceutical composition, makes this active ingredient very susceptible to adsorption to, e.g., the surfaces of laboratory glassware, vessels, to the vial in which the pharmaceutical composition is reconstituted and to the inside surface of a syringe used to inject the pharmaceutical composition. Such adsorption of a Clostridial toxin active ingredient to surfaces can lead to a loss of active ingredient and to denaturation of the remaining Clostridial toxin active ingredient, both of which reduce the total activity of the active ingredient present in the pharmaceutical composition. Hence, the use of non-protein excipients, such as, e.g., stabilizers, cryo-protectants and lyo-protectants must be able to act as surface blockers to prevent the adsorption of a Clostridial toxin active ingredient to a surface.

Yet another problem connected to a Clostridial toxin active ingredient, is the pH-sensitivity associates with complex formation. For example, the 900-kDa BoNT/A complex is known to be soluble in dilute aqueous solutions at pH 3.5-6.8. However, at a pH above about 7 the non-toxic associated proteins dissociate from the 150-kDa neurotoxin, resulting in a loss of toxicity, particularly as the pH rises above pH 8.0. See Edward J. Schantz et al., pp. 44-45, Preparation and characterization of botulinum toxin type A for human treatment, in Jankovic, J., et al., Therapy with Botulinum Toxin (Marcel Dekker, Inc., 1994). As the non-toxic associated proteins are believed to preserve or help stabilize the secondary and tertiary structures upon which toxicity is depends, the dissociation of these proteins results in a more unstable Clostridial toxin active ingredient. Thus, non-protein excipients useful to formulate a pharmaceutical composition comprising a Clostridial toxin active ingredient must be able to operate within the confines of a pH level necessary to maintain the activity a Clostridial toxin active ingredient.

What is needed therefore is a Clostridial toxin pharmaceutical composition wherein a Clostridial toxin active ingredient (such as a botulinum toxin) is stabilized by a non-protein excipient. The present invention relates to solid and liquid Clostridial toxin pharmaceutical compositions with one or more non-protein excipients which functions to stabilize the Clostridial toxin active ingredient present in the solid or liquid pharmaceutical composition.

Definitions

As used herein, the words or terms set forth below have the following definitions:

The articles “a” and “an” are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element.

“About” or “approximately” as used herein means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, (i.e., the limitations of the measurement system). For example, “about” can mean within 1 or more than 1 standard deviations, per practice in the art. Where particular values are described in the application and claims, unless otherwise stated, the term “about” means within an acceptable error range for the particular value.

“Administration”, or “to administer” means the step of giving (i.e. administering) a pharmaceutical composition to a subject, or alternatively a subject receiving a pharmaceutical composition. The pharmaceutical compositions disclosed herein can be locally administered by various methods. For example, intramuscular, intradermal, subcutaneous administration, intrathecal administration, intraperitoneal administration, topical (transdermal), instillation, and implantation (for example, of a slow-release device such as polymeric implant or miniosmotic pump) can all be appropriate routes of administration.

“Alleviating” means a reduction in the occurrence of a pain, of a headache, or of any symptom or cause of a condition or disorder. Thus, alleviating includes some reduction, significant reduction, near total reduction, and total reduction.

“Animal protein free” means the absence of blood derived, blood pooled and other animal derived products or compounds. “Animal” means a mammal (such as a human), bird, reptile, fish, insect, spider or other animal species. “Animal” excludes microorganisms, such as bacteria. Thus, an animal protein free pharmaceutical composition can include a botulinum neurotoxin. For example, an “animal protein free” pharmaceutical composition means a pharmaceutical composition which is either substantially free or essentially free or entirely free of a serum derived albumin, gelatin and other animal derived proteins, such as immunoglobulins. An example of an animal protein free pharmaceutical composition is a pharmaceutical composition which comprises or which consists of a botulinum toxin (as the active ingredient) and a suitable polysaccharide as a stabilizer or excipient.

“Antioxidant” refers to any compound which protects an active ingredient from reaction with oxygen. Antioxidants can be broadly divided into three categories: (i) sacrificial antioxidants, which react with oxygen more readily than a particular active ingredient and therefore can scavenge oxygen, e.g., ascorbic acid and sulfites; (ii) chain terminators, which are molecules that form stable radicals due to weak bonds to hydrogen atoms that are attacked in a propagation of radical chains by consumption of oxygen, e.g., methionine, NAC, glutathionine, lipoic acid, butylated hydroxytoluene (BHT), and cysteine, (iii) chelating agents, which reduce catalytic activity of transition metals by forming complexes with the metals, e.g., EDTA, EGTA and DTPA and analogs thereof.

“Biological activity” describes the beneficial or adverse effects of a drug on living matter. When a drug is a complex chemical mixture, this activity is exerted by the substance's active ingredient but can be modified by the other constituents. Biological activity can be assessed as potency or as toxicity by an in vivo LD₅₀ or ED₅₀ assay, or through an in vitro assay such as, for example, cell-based potency assays (CBPAs) as described in U.S. 20100203559 and U.S. 20100233802. The activities of the compositions of the invention may be measured using any sutiable assay and are not limited to activities measured by CBPA. The potency described in the examples also encompasses potency when measured using LD50.

“Botulinum toxin” means a neurotoxin produced by Clostridium botulinum, as well as a botulinum toxin (or the light chain or the heavy chain thereof) made recombinantly by a non-Clostridial species. The phrase “botulinum toxin”, as used herein, encompasses the botulinum toxin serotypes A, B, C, D, E, F and G, and their subtypes and any other types of subtypes thereof, or any re-engineered proteins, analogs, derivatives, homologs, parts, sub-parts, variants, or versions, in each case, of any of the foregoing. “Botulinum toxin”, as used herein, also encompasses a “modified botulinum toxin”. Further “botulinum toxin” as used herein also encompasses a botulinum toxin complex, (for example, the 300, 600 and 900 kDa complexes), as well as the neurotoxic component of the botulinum toxin (150 kDa) that is unassociated with the complex proteins.

“Clostridial toxin” refers to any toxin produced by a Clostridial toxin strain that can execute the overall cellular mechanism whereby a Clostridial toxin intoxicates a cell and encompasses the binding of a Clostridial toxin to a low or high affinity Clostridial toxin receptor, the internalization of the toxin/receptor complex, the translocation of the Clostridial toxin light chain into the cytoplasm and the enzymatic modification of a Clostridial toxin substrate. Non-limiting examples of Clostridial toxins include a Botulinum toxin like BoNT/A, a BoNT/B, a BoNT/C₁, a BoNT/D, a BoNT/E, a BoNT/F, a BoNT/G, a Tetanus toxin (TeNT), a Baratii toxin (BaNT), and a Butyricum toxin (BuNT). The BoNT/C₂ cytotoxin and BoNT/C₃ cytotoxin, not being neurotoxins, are excluded from the term “Clostridial toxin.” A Clostridial toxin disclosed herein includes, without limitation, naturally occurring Clostridial toxin variants, such as, e.g., Clostridial toxin isoforms and Clostridial toxin subtypes; non-naturally occurring Clostridial toxin variants, such as, e.g., conservative Clostridial toxin variants, non-conservative Clostridial toxin variants, Clostridial toxin chimeric variants and active Clostridial toxin fragments thereof, or any combination thereof. A Clostridial toxin disclosed herein also includes a Clostridial toxin complex. As used herein, the term “Clostridial toxin complex” refers to a complex comprising a Clostridial toxin and non-toxin associated proteins (NAPs), such as, e.g., a Botulinum toxin complex, a Tetanus toxin complex, a Baratii toxin complex, and a Butyricum toxin complex. Non-limiting examples of Clostridial toxin complexes include those produced by a Clostridium botulinum, such as, e.g., a 900-kDa BoNT/A complex, a 500-kDa BoNT/A complex, a 300-kDa BoNT/A complex, a 500-kDa BoNT/B complex, a 500-kDa BoNT/C₁ complex, a 500-kDa BoNT/D complex, a 300-kDa BoNT/D complex, a 300-kDa BoNT/E complex, and a 300-kDa BoNT/F complex.

“Clostridial toxin active ingredient” refers to a molecule which contains any part of a clostridial toxin that exerts an effect upon or after administration to a subject or patient. As used herein, the term “clostridial toxin active ingredient” encompasses a Clostridial toxin complex comprising the approximately 150-kDa Clostridial toxin and other proteins collectively called non-toxin associated proteins (NAPs), the approximately 150-kDa Clostridial toxin alone, or a modified Clostridial toxin, such as, e.g., a re-targeted Clostridial toxins.

“Deformity” means a cosmetic, physical or functional irregularity, defect, abnormality, imperfection, malformation, depression, or distortion.

“Effective amount” as applied to the biologically active ingredient means that amount of the ingredient which is generally sufficient to effect a desired change in the subject. For example, where the desired effect is a reduction in an autoimmune disorder symptom, an effective amount of the ingredient is that amount which causes at least a substantial reduction of the autoimmune disorder symptom, and without resulting in significant toxicity.

“Effective amount” when used in reference to the amount of an excipient or specific combination of excipients added to a Clostridial toxin composition, refers to the amount of each excipient that is necessary to achieve the desired initial recovered potency of a Clostridial toxin active ingredient. In aspects of this embodiment, an effective amount of an excipient or combination of excipients results in an initial recovered potency of, e.g., at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90% or at least 100%.

“Heavy chain” means the heavy chain of a botulinum neurotoxin. It has a molecular weight of about 100 kDa and can be referred to as the H chain, or as H.

He means a fragment (about 50 kDa) derived from the H chain of a botulinum neurotoxin which is approximately equivalent to the carboxyl end segment of the H chain, or the portion corresponding to that fragment in the intact H chain. It is believed to be immunogenic and to contain the portion of the natural or wild type botulinum neurotoxin involved in high affinity, presynaptic binding to motor neurons.

H_(N) means a fragment (about 50 kDa) derived from the H chain of a botulinum neurotoxin which is approximately equivalent to the amino end segment of the H chain, or the portion corresponding to that fragment in the intact in the H chain. It is believed to contain the portion of the natural or wild type botulinum neurotoxin involved in the translocation of the L chain across an intracellular endosomal membrane.

“Light chain” means the light chain of a clostridial neurotoxin. It has a molecular weight of about 50 kDa, and can be referred to as the L chain, L, or as the proteolytic domain (amino acid sequence) of a botulinum neurotoxin.

LH_(N) or L-H_(N) means a fragment derived from a clostridial neurotoxin that contains the L chain, or a functional fragment thereof coupled to the H_(N) domain It can be obtained from the intact clostridial neurotoxin by proteolysis, so as to remove or to modify the He domain.

“Implant” means a controlled release (e.g., pulsatile or continuous) composition or drug delivery system. The implant can be, for example, injected, inserted or implanted into a human body.

“Liquid composition”, “liquid pharmaceutical composition”, or “liquid formulation” refers to a pharmaceutically active preparation of drug or biologically active ingredient which is capable of being stored in a liquid pharmaceutical excipient, such as a buffering agent, for an extended period of time, such that it can be ready-to-use as needed by a clinician. The liquid pharmaceutical composition is manufactured without a lyophilization process.

“Local administration” means direct administration of a pharmaceutical at or to the vicinity of a site on or within an animal body, at which site a biological effect of the pharmaceutical is desired, such as via, for example, intramuscular or intra- or subdermal injection or topical administration.

Local administration excludes systemic routes of administration, such as intravenous or oral administration. Topical administration is a type of local administration in which a pharmaceutical agent is applied to a patient's skin.

“Lyoprotector” or “lyoprotectant” means a substance that is included in a lyophilized formulation to protect a Clostridial toxin active ingredient during the freeze-drying process. Lyoprotectors include for example polyhydroxy compounds such as sugars (mono-, di-, and polysaccharides), polyalcohols, and their derivatives. Exemplary lyoprotectors which can be used with the lyophilized formulations disclosed herein include sucrose, trehalose, mannitol, sorbitol, glucose, raffinose, maltose, glycerol, lactose, fructose, galactose, and combinations thereof.

“Lyophilized composition”, “lyophilized pharmaceutical composition”, “lyophilized formulation”, or “solid composition” refers to a formulation containing a Clostridial toxin active ingredient which has been subjected to a lyophilization, freeze-drying or vacuum-drying process; and can be reconstituted with a reconstitution vehicle, such as for example saline or water, prior to administration to a patient. The lyophilized composition can be a freeze-dried composition or a vacuum-dried composition.

“Modified botulinum toxin” means a botulinum toxin that has had at least one of its amino acids deleted, modified, or replaced, as compared to a native botulinum toxin. Additionally, the modified botulinum toxin can be a recombinantly produced neurotoxin, or a derivative or fragment of a recombinantly made neurotoxin. A modified botulinum toxin retains at least one biological activity of the native botulinum toxin, such as, the ability to bind to a botulinum toxin receptor, or the ability to inhibit neurotransmitter release from a neuron. One example of a modified botulinum toxin is a botulinum toxin that has a light chain from one botulinum toxin serotype (such as serotype A), and a heavy chain from a different botulinum toxin serotype (such as serotype B). Another example of a modified botulinum toxin is a botulinum toxin coupled to a neurotransmitter, such as substance P.

“Mutation” means a structural modification of a naturally occurring protein or nucleic acid sequence. For example, in the case of nucleic acid mutations, a mutation can be a deletion, addition or substitution of one or more nucleotides in the DNA sequence. In the case of a protein sequence mutation, the mutation can be a deletion, addition or substitution of one or more amino acids in a protein sequence. For example, a specific amino acid comprising a protein sequence can be substituted for another amino acid, for example, an amino acid selected from a group which includes the amino acids alanine, aspargine, cysteine, aspartic acid, glutamic acid, phenylalanine, glycine, histidine, isoleucine, lysine, leucine, methionine, proline, glutamine, arginine, serine, threonine, valine, tryptophan, tyrosine or any other natural or non-naturally occurring amino acid or chemically modified amino acids. Mutations to a protein sequence can be the result of mutations to DNA sequences that when transcribed, and the resulting mRNA translated, produce the mutated protein sequence. Mutations to a protein sequence can also be created by fusing a peptide sequence containing the desired mutation to a desired protein sequence.

“Patient” means a human or non-human subject receiving medical or veterinary care. Accordingly, the compositions as disclosed herein can be used in treating any animal, such as, for example, mammals, or the like.

“Peripherally administering” or “peripheral administration” means subdermal, intradermal, transdermal, or subcutaneous administration, but excludes intramuscular administration. “Peripheral” means in a subdermal location, and excludes visceral sites.

“Pharmaceutical composition” means a composition comprising an active pharmaceutical ingredient, such as, for example, a clostridial toxin active ingredient such as a botulinum toxin, and at least one additional ingredient, such as, for example, a stabilizer or excipient or the like. A pharmaceutical composition is therefore a formulation which is suitable for diagnostic or therapeutic administration to a subject, such as a human patient. The pharmaceutical composition can be, for example, in a lyophilized or vacuum dried condition, a solution formed after reconstitution of the lyophilized or vacuum dried pharmaceutical composition, or as a solution or solid which does not require reconstitution.

“Pharmacologically acceptable excipient” is synonymous with “pharmacological excipient” or “excipient” and refers to any excipient that has substantially no long term or permanent detrimental effect when administered to mammal and encompasses compounds such as, e.g., stabilizing agent, a bulking agent, a cryo-protectant, a lyo-protectant, an additive, a vehicle, a carrier, a diluent, or an auxiliary. An excipient generally is mixed with an active ingredient, or permitted to dilute or enclose the active ingredient and can be a solid, semi-solid, or liquid agent. It is also envisioned that a pharmaceutical composition comprising a Clostridial toxin active ingredient can include one or more pharmaceutically acceptable excipients that facilitate processing of an active ingredient into pharmaceutically acceptable compositions. Insofar as any pharmacologically acceptable excipient is not incompatible with the Clostridial toxin active ingredient, its use in pharmaceutically acceptable compositions is contemplated. Non-limiting examples of pharmacologically acceptable excipients can be found in, e.g., Pharmaceutical Dosage Forms and Drug Delivery Systems (Howard C. Ansel et al., eds., Lippincott Williams & Wilkins Publishers, 7^(th) ed. 1999); Remington: The Science and Practice of Pharmacy (Alfonso R. Gennaro ed., Lippincott, Williams & Wilkins, 20^(th) ed. 2000); Goodman & Gilman's The Pharmacological Basis of Therapeutics (Joel G. Hardman et al., eds., McGraw-Hill Professional, 10^(th) ed. 2001); and Handbook of Pharmaceutical Excipients (Raymond C. Rowe et al., APhA Publications, 4^(th) edition 2003), each of which is hereby incorporated by reference in its entirety.

The constituent ingredients of a pharmaceutical composition can be included in a single composition (that is, all the constituent ingredients, except for any required reconstitution fluid, are present at the time of initial compounding of the pharmaceutical composition) or as a two-component system, for example a vacuum-dried composition reconstituted with a reconstitution vehicle which can, for example, contain an ingredient not present in the initial compounding of the pharmaceutical composition. A two-component system can provide several benefits, including that of allowing incorporation of ingredients which are not sufficiently compatible for long-term shelf storage with the first component of the two component system. For example, the reconstitution vehicle may include a preservative which provides sufficient protection against microbial growth for the use period, for example one-week of refrigerated storage, but is not present during the two-year freezer storage period during which time it might degrade the toxin. Other ingredients, which may not be compatible with a botulinum toxin or other ingredients for long periods of time, can be incorporated in this manner; that is, added in a second vehicle (e.g. in the reconstitution vehicle) at the approximate time of use. A pharmaceutical composition can also include preservative agents such as benzyl alcohol, benzoic acid, phenol, parabens and sorbic acid. Pharmaceutical compositions can include, for example, excipients, such as surface active agents; dispersing agents; inert diluents; granulating and disintegrating agents; binding agents; lubricating agents; preservatives; physiologically degradable compositions such as gelatin; aqueous vehicles and solvents; oily vehicles and solvents; suspending agents; dispersing or wetting agents; emulsifying agents, demulcents; buffers; salts; thickening agents; fillers; antioxidants; stabilizing agents; and pharmaceutically acceptable polymeric or hydrophobic materials and other ingredients known in the art and described, for example in Genaro, ed., 1985, Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pa., which is incorporated herein by reference.

“Polysaccharide” means a polymer of more than two saccharide molecule monomers. The monomers can be identical or different.

“Stabilizing agent”, “stabilization agent” or “stabilizer” means a substance that acts to stabilize a Clostridial toxin active ingredient such that the potency of the pharmaceutical composition is increased relative to an unstabilized composition.

“Stabilizers” can include excipients, and can include protein and non-protein molecules.

“Surfactant” refers to a natural or synthetic amphiphilic compound. A surfactant can be non-ionic, zwitterionic, or ionic. Non-limiting examples of surfactants include a poloxamer, a polysorbate, and combinations thereof.

“Therapeutic formulation” means a formulation can be used to treat and thereby alleviate a disorder or a disease, such as, for example, a disorder or a disease characterized by hyperactivity (i.e. spasticity) of a peripheral muscle.

“TEM” as used herein, is synonymous with “Targeted Exocytosis Modulator” or “retargeted endopeptidase.” Generally, a TEM comprises an enzymatic domain from a Clostridial toxin light chain, a translocation domain from a Clostridial toxin heavy chain, and a targeting domain. The targeting domain of a TEM provides an altered cell targeting capability that targets the molecule to a receptor other than the native Clostridial toxin receptor utilized by a naturally-occurring Clostridial toxin. This re-targeted capability is achieved by replacing the naturally-occurring binding domain of a Clostridial toxin with a targeting domain having a binding activity for a non-Clostridial toxin receptor. Although binding to a non-Clostridial toxin receptor, a TEM undergoes all the other steps of the intoxication process including internalization of the TEM/receptor complex into the cytoplasm, formation of the pore in the vesicle membrane and di-chain molecule, translocation of the enzymatic domain into the cytoplasm, and exerting a proteolytic effect on a component of the SNARE complex of the target cell.

“Tonicity agent” or “isotonic agent” means a low molecular weight excipient which is included in a lyophilized or liquid formulation to provide isotonicity. For example, a disaccharide such as trehalose or sucrose, a polyalcohol such as sorbitol or mannitol, a monosaccharide such as glucose, and a salt such as sodium chloride, can serve as a tonicity agent.

“Topical administration” excludes systemic administration of the neurotoxin. In other words, and unlike conventional therapeutic transdermal methods, topical administration of botulinum toxin does not result in significant amounts, such as the majority of, the neurotoxin passing into the circulatory system of the patient.

“Treating” means to alleviate (or to eliminate) at least one symptom of a condition or disorder, such as, for example, wrinkles, spasticity, depression, pain (such as, for example, headache pain), bladder overactivity, or the like, either temporarily or permanently.

As used herein, the term “unit” or “U” refers to the LD₅₀ dose or the dose determined by a cell based potency assay (CBPA). The LD₅₀ dose is defined as the amount of a Clostridial toxin active ingredient, Clostridial toxin complex or modified Clostridial toxin that killed 50% of the mice injected with the Clostridial toxin, Clostridial toxin complex or modified Clostridial toxin. The CBPA dose is determined as described in U.S. Pat. No. 8,618,261, the assay details of which are incorporated by reference herein.

“Variant” means a clostridial neurotoxin, such as wild-type botulinum toxin serotype A, B, C, D, E, F or G, that has been modified by the replacement, modification, addition or deletion of at least one amino acid relative to wild-type botulinum toxin, which is recognized by a target cell, internalized by the target cell, and catalytically cleaves a SNARE (SNAP (Soluble NSF Attachment Protein) Receptor) protein in the target cell.

An example of a variant neurotoxin component can comprise a variant light chain of a botulinum toxin having one or more amino acids substituted, modified, deleted and/or added. This variant light chain may have the same or better ability to prevent exocytosis, for example, the release of neurotransmitter vesicles. Additionally, the biological effect of a variant may be decreased compared to the parent chemical entity. For example, a variant light chain of a botulinum toxin type A having an amino acid sequence removed may have a shorter biological persistence than that of the parent (or native) botulinum toxin type A light chain.

In one aspect, the composition does not comprise a sugar or polyalcohol. Sugar is defined in the next section. As used herein, the term “polyalcohol” is synonymous with “sugar alcohol,” “polyhydric alcohol,” and “polyol” and refers to a sugar derivative having an alcohol group (CH₂OH) instead of the aldehyde group (CHO), such as, e.g., mannitol from mannose, xylitol from xylose, and lactitol from lactulose. Non-limiting examples of polyols include, glycol, glycerol, arabitol, erythritol, xylitol, maltitol, sorbitol (gluctiol), mannitol, inositol, lactitol, galactitol (iditol), isomalt. Other non-limiting examples of sugar excipients can be found in, e.g., Ansel, supra, (1999); Gennaro, supra, (2000); Hardman, supra, (2001); and Rowe, supra, (2003), each of which is hereby incorporated by reference in its entirety.

Treatment of Skin Conditions

A method within the scope of the present invention for treating a skin disorder can have the step of local administration of a botulinum neurotoxin to a location of a skin disorder of a patient, such as to a face, hand or foot of a patient. The neurotoxin can be locally administered in an amount of between about 10-3 units/kg of patient weight and about 35 units/kg of patient weight. For example, the neurotoxin is locally administered in an amount of between about 10-2 U/kg and about 25 U/kg of patient weight. In a further example, the neurotoxin is administered in an amount of between about 10-1 U/kg and about 15 U/kg. In one method within the scope of the present invention, the neurotoxin is locally administered in an amount of between about 1 U/kg and about 10 U/kg. In a clinical setting it can be advantageous to administer from 1 U to 3000 U of a neurotoxin, such as botulinum toxin type A or B, to a skin disorder location by topical application or by subdermal administration, to effectively treat the skin disorder.

Administration of botulinum toxin can be carried out at multiple sites in the skin, wherein the sites of adjacent injections are separated by about 0.1 to 10 cm, or about 0.5 to about 5 cm, for example, by about 1.5 to about 3 cm. The toxins may be any of the botulinum toxins A, B, C, D, E, F or G. The amounts administered may vary between 0.1 and 1000 U, or about 1 to about 40, or from about 5 to about 10 U, depending on the manufactures specifications, the class of the toxin and the mode of administration. The repeat time range for these administrations for maintenance of the desired change varies substantially according to the location of the injection, the condition to be adjusted and the condition of the patient. Thus the repeat time may vary from about 1 week to about 50 weeks, however a common range is about 4 to about 25 weeks, or even about 12 weeks to about 16 weeks.

The distances between administrations, for example, injections, can vary from about 1 mm to about 10 cm, suitably from about 5 mm to about 5 cm, and more usually from about 1 cm to about 3 cm. Thus for example botulinum A may be suitably administered by intradermal injection between about 0.1 to about 10 U at a separation of from about 0.5 to about 10 cm.

Example 1 Activities and Stabilities of Exemplary Solid Clostridial Pharmaceutical Compositions Relative to Prior Art Formulations

Bulk solutions of botulinum toxin were prepared by mixing an appropriate aliquot of a botulinum toxin type A with several vehicle solutions as described in the following Tables 1-3. The solutions were filled into glass vials and lyophilized using conventional freeze-drying conditions. Potency of the lyophilized formulations was tested by a cell based potency assay (CBPA) after reconstitution of the lyophiles with saline. Potency recovery results after freeze-drying and after storage at indicated temperatures are provided in the tables and normalized to target potency. The potencies of the solid compositions prepared according to aspects of the present invention were compared to three comparative formulations as shown in Tables 1-3.

Example 2 Activities of Liquid Clostridial Pharmaceutical Compositions in the Presence or Absence of Antioxidants

Bulk drug product solutions were prepared by mixing an appropriate aliquot of a botulinum toxin type A with three different vehicle solutions as shown in Table 4. All three formulations contained 8% w/w trehalose, 4% w/w P188 and 20 mM Histidine buffer at pH 6.0. The target potency was 100 units/mL. Formulation 10 contained no antioxidant. Formulations 11 and 12 contained NAC and methionine, respectively. The bulk solutions were filled into 2 mL glass vials (1.25 mL fill), and sealed with rubber stopper and aluminum shell. Potency of the formulations was tested by a cell based potency assay (CBPA) after filling (time zero, t0) and storage for one month at four temperatures (−70, 5, 25, and 40° C.). Potency test results are given in Table 4. Briefly, methionine-containing formulation (#12) retained its potency after one month storage at all four temperatures, including 40° C., whereas the formulation w/o an antioxidant lost approx. 17% potency at 25° C. and lost essentially all activity (i.e., complete inactivation) at 40° C. A second antioxidant tested, N-acetyl-L-cysteine, accelerated loss of potency as compared with the antioxidant-free formulation, demonstrating that N-acetyl-L-cysteine acted as pro-oxidant in this formulation. The liquid composition comprising NAC lost over 50% potency after storage for 1 month at 25° C. and lost essentially all activity (i.e., complete inactivation of the toxin) after storage for 1 month at 40° C. In contrast, as shown in Table 1, the lyophilized compositions comprising NAC lost 7% ((98.6%-91.9%)/98.6%) potency after storage for 3 months at 25° C. and lost 12% ((98.6%-86.5%)/98.6%) potency after storage for 1 month at 40° C. This demonstrates that NAC can function as a stabilizer in the lyophilized compositions.

Example 3 Impact of Exemplary Antioxidants on the Stability of Exemplary Liquid Formulations

Bulk drug product solutions were prepared by mixing an appropriate aliquot of a botulinum toxin type A with different antioxidants as shown in Table 5. All formulations contained 8% w/w trehalose, 4% w/w P188, 20 mM Histidine buffer at pH 6.0 and one or more antioxidants as listed. Target potency was 100 U/mL. The bulk solutions were filled into 2 mL glass vials (1.25 mL fill), and sealed with rubber stopper and aluminum shell. Potency of the formulations was tested by a cell based potency assay (CBPA) after filling (time zero, t0) and storage for two weeks and 1 month at 40° C. Potency test results are given in Table 5. Liquid compositions comprising NAC and EDTA sodium salt (Formulation 26) retained full potency after storage at 40° C. for 2 weeks and 1 month, as did a composition comprising NAC, EDTA sodium salt and tryptophan (Formulation 27). In contrast, as shown in Table 5, liquid compositions comprising NAC but not EDTA (Formulation 25) lost essentially all potency after 2 weeks storage at 40° C. This demonstrates that the combination of antioxidants—a chelating agent (e.g., EDTA, EGTA or DTPA) and/or a chain terminator antioxidant (e.g., methionine, cysteine, NAC and BHT) provides a stabilizing effect on the botulinum toxin.

Example 4 Impact of Choice of Surfactant on the Stability of Exemplary Liquid Compositions

Bulk drug product solutions were prepared by mixing an appropriate aliquot of a botulinum toxin type A with a poloxamer or a polysorbate as shown in Table 6. All formulations contained 8% w/w trehalose, 0.2% w/w methionine in 20 mM Histidine buffer at pH 6.0 and 4% w/w P188 or 0.04% w/w Tween-20 as listed. Target potency was 100 U/mL. The bulk solutions were filled into 2 mL glass vials (1.25 mL fill), and sealed with rubber stopper and aluminum shell. Potency of the formulations was tested by a cell based potency assay (CBPA) after filling to give an initial potency. Potency was measured again after storage for 1 month at 40° C. Potency test results are given in Table 6. As is evident from the results in table 6, the liquid formulation comprising poloxamer provided improved stability after storage at 40° C. for one month relative to the corresponding formulation comprising polysorbate.

Example 5 Impact of Absence of Tonicity Agent on the Stability of Exemplary Liquid Compositions

Bulk drug product solutions were prepared by mixing an appropriate aliquot of a botulinum toxin type A with different components as shown in Tables 7 and 8. The amounts of components contained were 0% or 8% w/w trehalose, 0% or 0.2% w/w methionine, 0% or 4% w/w P188, all of which were formulated in 20 mM Histidine buffer at pH 6.0. Target potency was 100, 150, or 200 U/mL. The bulk solutions were filled into 2 mL glass vials (1.25 mL fill), and sealed with rubber stopper and aluminum shell. Potency of the formulations was tested by a cell based potency assay (CBPA) after filling to give an initial potency. Potency was measured again after storage for 1 month at −70° C. and 40° C. Potency test results are given in Tables 7 and 8. As is evident from the results in these tables, liquid formulations comprising poloxamer and no tonicity agent provide excellent stability after storage for one month at −70° C. and 40° C. This is supported by the results in table 10 below for formulation 40. Meanwhile, liquid formulations comprising polysorbate and no tonicity agent provide some stability after storage for one month at −70° C.

Example 7 Impact of Choice of Sugar on Stability of Exemplary Lyophilized Formulations

Bulk solutions of botulinum toxin were prepared by mixing an appropriate aliquot of a botulinum toxin type A with several vehicle solutions as described in Table 11. The amounts of components contained were 0% or 8% w/w trehalose or sucrose, 0.2% w/w methionine, 0% or 4% w/w P188, 0% or 0.04% w/w Tween 20 all of which were formulated in 20 mM Histidine buffer at pH 6.0. Target potency was 200 U/mL. These amounts are shown in Table 11 below. The solutions were filled into glass vials and lyophilized using conventional freeze-drying conditions. Potency of the lyophilized formulations was tested by a cell based potency assay (CBPA) after reconstitution of the lyophilized compositions after storage for 2 weeks at −70° C. or 40° C. Potency recovery results are given in Table 12. By comparing Formulation No. 42 with Formulation No. 44 and Formulation No. 43 with Formulation No. 45, the impact of the type of sugar on these lyophilized formulations can be derived. The potency of the botulinum toxin in Formulation 42 and in Formulation 44 after 2 weeks of storage at −20° C. and at 40° C. reveals a higher potency recovery was achieved in lyophilized compositions comprising trehalose, as compared to lyophilized compositions comprising sucrose.
